Abstract: A control circuit for electric regenerative power take-off includes: instant voltage and current sensors for connecting to power connection of a synchronous generator for capturing a triphasic voltage and a triphasic current, respectively; voltage-based and current-based direct-quadrature (“DQ”) transform calculators outputting an equivalent two phase DQ tensor of a three vector triphasic voltage of the captured voltage and an equivalent two phase DQ tensor of a three vector triphasic current of the captured current, respectively; a current-based DQ controller outputting “desired” active-power and reactive-power voltages for the power controller; a phase-locked loop (“PLL”) for defining the operation angle of the power converter; processor switching between 1st and 2nd operation stages in order to engage or disengage the power converter from the synchronous generator, and to synchronize the PLL with the captured voltage using “Q output” from either the voltage-based DQ transform calculator or the current-base

Abstract: An energy harvesting device for a transport vehicle comprising an electric converter circuit and a power take-off unit is disclosed. The electric converter circuit comprises: an electric energy storage; a first DC bus; an electric generator connected to the first DC bus through an electronic brake controller; a second DC bus connected to the first DC bus through a DC/DC converter, and an inverter connected to the second DC bus and having an output connected to the electrical load of the energy harvesting device.
